TECHNICAL FIELD

Embodiments of the present invention are directed to a system and method for application and infrastructure analysis and forecasting with the goal of improving the performance of the application and infrastructure and reducing complexity of analyzing such performance.

BACKGROUND OF THE INVENTION

When applications and/or systems are developed and deployed onto an enterprise network infrastructure, system performance often suffers if an application has been designed without careful regard for distance between tiers, underlying transport protocols, message flows, network configuration and dynamics, etc. Similarly when new systems are placed onto the network, their configuration often needs to be managed or optimized to obtain the performance required. Furthermore, during system configuration and deployment, often times there is a need for quantification of the performance that can be expected from the system configuration.

Existing commercial products let an expert study the impact of various system design parameters, such as, distance between tiers, underlying transport protocols, application parameters, etc., on the final performance of an application system. However, these commercial products require advanced expertise in system design and configuration from the interacting user. As a result, the existing products are far more involved to use and cannot be readily leveraged by application designers or deployment engineers.

Thus, there is a need for an application and infrastructure performance analysis and forecasting system that bridges the gap between the consumers of the analysis (application designers and deployment engineers) and the expertise embodied in the invention. That is, there is a need for a comprehensive and easy-to-use application and infrastructure performance analysis and forecasting system that provides the same advisory expertise for application designers and deployment engineers, as can be used by experts with advanced knowledge in this field.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Embodiments of the present invention are directed to a system and method for an Application and Infrastructure Performance Analysis and Forecasting Manager that improves the performance of an application and corresponding infrastructure, and further reduces the complexity of analyzing such performance. The system and method receive input from the user regarding their system configuration and performance objectives. Based on the user input, the system and method decide which application and infrastructure performance model to apply to the user's system. For each identified model, the system and method then gather model-specific input(s) from the user. The system and method then calculate model-specific results and display them to the user.

FIG. 1A is a block diagram illustrating an operating environment for an Application and Infrastructure Performance Analysis and Forecasting System in accordance with an embodiment of the invention. The Application and Infrastructure Performance Analysis and Forecasting System 70 is connected through a communications medium over a Network 30, such as the internet, an intranet, a local-area-network (LAN), a wide-area-network (WAN), etc., to one or more Web Dashboard(s) 20 at one or more Display Device(s) 60. The Web Dashboard(s) 20 may allow a user to enter information regarding application and infrastructure configuration, performance objective(s), and model-specific details.

The Application and Infrastructure Performance Analysis and Forecasting System 70 includes a Data Store 40, a Modeling Engine 100, and a Model Computation Engine 110. In an embodiment of the invention, the Data Store 40 may be a database that is local to the Application and Infrastructure Performance Analysis and Forecasting System 70 and that stores data to be used by the Application and Infrastructure Performance Analysis and Forecasting System 70 to perform the performance optimization of an application and infrastructure.

A user may access the Web Dashboard 20 using a web browser. In an embodiment of the invention, a user is prompted to provide authentication information before access to the Web Dashboard 20 is granted. Examples of authentication information include, but are not limited to, username, user id, password, biometrics, etc. Once a user is authenticated, he/she may be able to perform several actions using the Web Dashboard(s) 20. For example, a user may be able to enter information regarding their system configuration and performance objectives. A Web Dashboard for receiving information regarding system configuration and performance objectives is described in greater detail in reference with FIGS. 4A and 4B.

After receiving such input, the Modeling Engine 100 may determine at least one application and infrastructure performance model to perform performance analysis and forecasting of the user's system configuration. The Modeling Engine 100 may consider one or more factors in determining which application and infrastructure performance model to present to the user. Examples of such factors include, but are not limited to, system design, performance requirements, and system configuration. The Modeling Engine 100 may also make one or more assumptions when determining which application and infrastructure performance model to present to the user. Examples of assumed information include, but are not limited to, default values for one or more system design and/or configuration items, calculated values based on one or more user input items, etc. The Modeling Engine 100 may also determine the application and infrastructure performance model based on default values, prior input received from the user, user response history, etc.

For each application and infrastructure performance model identified by the Modeling Engine 100, the user may be presented with one or more Web Dashboard(s) 20 to gather additional information specific to each model. Examples of Web Dashboard(s) 20 for receiving information regarding each application and infrastructure performance model are described in greater detail in reference with FIGS. 5A, 6A, 7A, 8A, 9A, and 10A. After receiving model-specific input from the user, the Model Computation Engine 110 may compute model-specific output. The model specific output may be based on one or more inputs received from the user. The model specific output may also be based on assumed information. Examples of assumed information include, but are not limited to, default values for one or more system design and/or configuration items, calculated values based on one or more user input items, etc. The model specific output may then be displayed at one or more Web Dashboard(s) 20. Examples of Web Dashboard(s) 20 for displaying model specific outputs are described in greater detail in reference with FIGS. 5B, 6B, 7B, 8B, 9B, and 10B.

In an embodiment of the invention, the Model Computation Engine 110 may evaluate the performance objectives provided by the user to determine one or more system design and/or system configuration parameters that may be modified to optimize the performance objectives. For example, if the user specifies a performance objective for a message round-trip time, the Model Computation Engine 110 may determine, based on the initial system design and configuration information, as well as the desired message round-trip time, one or more system design and/or configuration parameters (e.g., placement of transfer-end-points, transfer protocol to use, server parameters, etc.) that may be modified to achieve the desired performance objective. In an embodiment of the invention, the Model Computation may determine one or more of the following system design and/or system configuration parameters based on the performance objectives provided by the user: proper locations for application end-points (for example, which data centers to put application components into), maximum network route size/hops to assure messages delivery meets performance objectives, maximum network end-to-end latency that can be tolerated in meeting performance objectives, required network switch latencies given a route hop count and distances over the network route, minimum network bandwidth required to carry the application traffic over the network, and TCP window sizes required to meet performance objectives.

Those skilled in the art will appreciate that the invention may be practiced with various computer system configurations, including hand-held wireless devices such as mobile phones, smart phones or Personal Digital Assistants (PDAs) 150, multiprocessor systems 155, microprocessor-based or programmable consumer electronics 160, minicomputers 165, mainframe computers 170, Tablets (iPad™, Samsung Galaxy™, etc.) 175, and the like. The invention may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network 30. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.

Generally, it should be noted that the components depicted and described herein above may be, or include, a computer or multiple computers. Although the components are shown as discrete units, all components may be interconnected or combined. The components may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc., that perform particular tasks or implement particular abstract data types.

FIG. 2 is a flow chart illustrating a method for Application and Infrastructure Performance Analysis and Forecasting in accordance with an embodiment of the invention. The method begins at step 210 by receiving infrastructure input from a user regarding their system configuration and performance objectives. Examples of infrastructure input include, but are not limited to, system design, system configuration, and performance objectives. After receiving the infrastructure input from the user, the method determines, in step 220, at least one application and infrastructure performance model. Examples of application and infrastructure performance models include, but are not limited to, user response time model, bulk transfer model, message queue and database response time model, message delay and variation model, market data distribution model, and streaming model. The application and infrastructure performance model may be determined based on the infrastructure input provided by the user. The application and infrastructure performance model may also be determined based on default values, prior input received from the user, user response history, etc.

After determining at least one application and infrastructure performance model, the method, in step 230 receives model specific input from the user for each application and infrastructure performance model. Examples of model specific input include, but are not limited to, user-server configuration, round-trip time between transfer end points, number of objects sent to transfer end points, number of objects comprising a response, location of transfer end points, size of information being transferred, transfer time requirements, application used for transfer of data between transfer end points, size of at least one object transferred between transfer end points, information transfer protocol, mode of dataflow operation between transfer end times, information transfer rate, number of hops between transfer end points, measured round trip time between transfer end points, and type of information transfer. Examples of Web Dashboard(s) 20 for receiving information regarding each application and infrastructure performance model are described in greater detail in reference with FIGS. 5A, 6A, 7A, 8A, 9A, and 10A. In an embodiment of the invention, the model specific parameters for each application and infrastructure performance model may be obtained from memory (for example, a database).

The method may then compute, at step 240, at least one output for each application and infrastructure performance model using a Model Computation Engine. The model specific output may be based on one or more inputs received from the user. The inputs received from the user may be system design information, system configuration information, performance objective(s), and model specific input. The model specific output may also be based on assumed information. Examples of assumed information include, but are not limited to, default values for one or more system design and/or configuration items, calculated values based on one or more user input items, etc. The method may then display, at step 250, model specific output at one or more Web Dashboard(s) 20. The output may be numerical, visual, or audial. Examples of Web Dashboard(s) 20 for displaying model specific outputs are described in greater detail in reference with FIGS. 5B, 6B, 7B, 8B, 9B, and 10B. In an embodiment of the invention, the method transmits the model specific output to one or more remote locations over a network.

In an embodiment of the invention, the Model Computation Engine may evaluate the performance objectives provided by the user to determine one or more system design and/or system configuration parameters that may be modified to optimize the performance objectives. For example, if the user specifies a performance objective for a message round-trip time, the Model Computation Engine may determine, based on the initial system design and configuration information, as well as the desired message round-trip time, one or more system design and/or configuration parameters (e.g., placement of transfer-end-points, transfer protocol to use, server parameters, etc.) that may be modified to achieve the desired performance objective. In an embodiment of the invention, the Model Computation may determine one or more of the following system design and/or system configuration parameters based on the performance objectives provided by the user: proper locations for application end-points (for example, which data centers to put application components into), maximum network route size/hops to assure messages delivery meets performance objectives, maximum network end-to-end latency that can be tolerated in meeting performance objectives, required network switch latencies given a route hop count and distances over the network route, minimum network bandwidth required to carry the application traffic over the network, and TCP window sizes required to meet performance objectives.

FIG. 3 is a block diagram illustrating various Application and Infrastructure Performance Models 300 in accordance with an embodiment of the invention. Examples of application and infrastructure performance model include, but are not limited to, User Response Time Model 305, Bulk Transfer Model 310, Message Queue And Database Response Time Model 320, Message Delay And Variation Model 330, Market Data Distribution Model 340, and Streaming Model 350. The User Response Time Model 305 predicts the performance for web-page-like user transactions where the user operates a web-page or other client application that communicates with servers to complete a function. The User Response Time Model 305 may calculate the performance to be expected for elements of completing a user transaction against the servers. The Bulk Transfer Model 310 determines the amount of time required to transfer/copy large data blocks between transfer end points. It may also determine the amount of traffic that will be placed on the network by the transfers and advise on the impact of different transfer protocols. The Message Queue And Database Response Time Model 320 addresses the operation of messaging streams for message-queue or database queries as they traverse the network and are affected by flow-control and the network route and configuration. It may predict the time required to send messages and the volume of traffic they will generate on the network. It may also encompass the impact of TCP flow control on performance. The Message Delay And Variation Model 330 addresses the flow of objects from source to destination end points and focuses on the basic transfer of objects of a given size with time between messages. It may show how flow-control will affect message delivery times and how much traffic the messages add to the network. The Market Data Distribution Model 340 analyzes the performance of market data streaming from source to destination end points. It may advise the user about the impact of network hops on the source-to-destination message delivery latency and how much flow-control will impact performance. It may also advise regarding the impact of serialization latencies on end-to-end delivery times. The Streaming Model 350 predicts the performance when messages are streamed from source to destination end points using TCP and/or UDP protocols. It may include estimates on network traffic levels and message transfer times.

The User Response Time Model 305 may use the following information: location of transfer end points, network round-trip time, object size and number sent during a transaction between a user computer and a server, whether objects are sent in parallel or sequentially to the server, and whether objects are sent in parallel or sequentially from the server to the user. The User Response Time Model 305 may then, for each scenario of transmission to or from the server, calculate the time to transfer an object. The User Response Time Model 305 may also compute a transfer rate for the transmission. In an embodiment of the invention, the User Response Time Model 305 may use an analytic model of the Transmission Control Protocol/Internet Protocol (TCP/IP) transmission process to compute a model specific output. The TCP/IP transmission process may calculate the transmission time duration for an application object from a TCP/IP source to a destination. The TCP/IP transmission process may take into account at least the round-trip-time and TCP receive window size. The TCP/IP transmission process may also include packet loss probabilities pertaining to the network route and any bottleneck links in the network route. The TCP/IP transmission process may assume information such as, TCP/IP receive window, network round-trip time, object size to be sent between the transfer end-points, etc. Based on the TCP/IP transmission process calculations, the User Response Time Model 305 may then compute one or more metrics that may be produced to compute model specific output. Examples of some metrics are depicted below: Slope=(64000*8/measured network round-trip time between transfer end-points)/(6*measured network round-trip time between transfer end-points) Tput_(avg) (Throughput)=object size*8/(Time spent in steady-state phase after ramp-up+Time for the TCP/IP ramp-up process)

-   -   If object size*8<=Amount sent during linear ramp-up, then         Object Transmission Time=square-root(2*object size*8/Slope)     -   If object size>Amount sent during linear ramp-up, then         Object Transmission Time=Time spent in steady-state phase after         ramp-up+Time for the TCP/IP ramp-up process

The User Response Time Model 305 may calculate the time that will be required for the sending and receiving portions of a transaction. For example, if the transfers for the sending direction are sequential, then the User Response Time Model 305 may model the transfers as one long TCP/IP transmission. If the transfers for the sending direction are parallel, then the User Response Time Model 305 may model them as concurrent individual TCP/IP transmissions. Similar calculations may be performed for the receiving direction. The User Response Time Model 305 may compute the transfer duration as the sum of the time that will be required for sending duration and the time that will be required for receiving. The User Response Time Model 305 may also calculate a transaction run-time as the sum of the transfer duration and idle time, that is, time between transactions. The User Response Time Model 305 may also calculate the impact on the network by computing one or more outputs. Examples of such output may include: average traffic sent per user transaction, average traffic per user, average traffic received per user transaction, and network traffic. The outputs may be computed as follows: Average Traffic Sent Per User Transaction=Sent Object Size*Number Sent/Transaction Run-Time Average Traffic Per User=Average Traffic Sent Per User Transaction*transaction rate(transactions/second) Average Traffic Received Per User Transaction=Received Object Size*Number Received/Transaction Run-Time Network Traffic=Population Size*Average Traffic Per User

The User Response Time Model 305 may then generate one or more model specific outputs. Examples of User Response Time Model specific output include, but are not limited to, the time required to complete the transmission portion of a user transaction, and advice on traffic volumes the transaction will generate when driven by a population of users. An example of a model-specific output for a Message Queue And Database Response Time Model 320 is described in greater detail in reference with FIG. 5B.

The Bulk Transfer Model 310 may use the following information: location of transfer end points, network round-trip time, transfer size, whether there is a transfer-time requirement, and the application or protocol used for the transfer. Examples of application or protocols used for the transfer include, but are not limited to, File Transfer Protocol (FTP), backup appliances, Windows copies operations (xcopy, robocopy), WebSphere MQ-based file transfer, secure copy, bulk transfer, or other proprietary and/or commercial applications or protocols, etc. In an embodiment of the invention, the Bulk Transfer Model 310 may then compute data-rate (throughput) during a steady-state phase based on a TCP/IP transmission process.

In an embodiment of the invention, the Bulk Transfer Model 310 may compute the following metrics based on a TCP/IP transmission model shown in FIG. 11.

-   -   where,     -   rtt=measured network round-trip-time between connection         end-points     -   RWS=TCP/IP receive window size in bytes as advertised by the         receiver=64000 as per the common TCP default value         Tput_(ss) (data-rate (throughput) during the steady-state         phase)=RWS*8/rtt         T _(ramp-up) (time for the TCP/IP ramp-up process)=6*rtt         X _(ramp-up) (amount sent during the linear ramp-up)=(½)*T         _(ramp-up)*Tput_(ss)=1.536Mbits (for example)         X _(ss) (amount sent during the steady-state phase of         transmission)=object size*8−Xramp-up         T _(ss) (time sent in the steady-state phase after ramp-up)=X         _(ss)/Tput_(ss)     -   If object size*8<=Amount sent during linear ramp-up, then         Object Transmission Time=square-root(2*object size*8/Slope)     -   If object size>Amount sent during linear ramp-up, then         Object Transmission Time=Time spent in steady-state phase after         ramp-up+Time for the TCP/IP ramp-up process

The Bulk Transfer Model 310 may further calculate the time that will be required for the object transfer. For example, if the transfers for the sending direction are sequential, then the Bulk Transfer Model 310 may model the transfers as one long TCP/IP transmission. If the transfers for the sending direction are parallel, then the Bulk Transfer Model 310 may model them as concurrent individual TCP/IP transmissions. Similar calculations may be performed for the receiving direction. The Bulk Transfer Model 310 may compute the transfer duration as the sum of the time that will be required for sending duration and the time that will be required for receiving. The Bulk Transfer Model 310 may also calculate a transaction run-time as the sum of the transfer duration and idle time, that is, time between transactions. The Bulk Transfer Model 310 may further compute the network traffic as equivalent to the steady-state throughput for the duration of the transfer.

The Bulk Transfer Model 310 may then generate one or more model specific outputs. Examples of Bulk Transfer Model specific output include, but are not limited to, the time to transfer an object using specified and default setting parameters, advice on whether or not the transfer of the specified bulk data will saturate network links, advice on whether or not FTP will handle the transfer size and whether or not traffic throttles should be used. An example of a model-specific output for a Bulk Transfer Model 310 is described in greater detail in reference with FIG. 6B.

The Message Queue And Database Response Time Model 320 may use the following information: location of transfer end points, network round-trip time, whether messaging is synchronous/sequential versus asynchronous/parallel/overlapping, and message size estimates. The Message Queue And Database Response Time Model 320 may calculate one or more metrics based on a TCP/IP transmission process. Examples of some metrics are depicted below: Slope=(64000*8/measured network round-trip time between transfer end-points)/(6*measured network round-trip time between transfer end-points) Tput_(avg) (Throughput)=message size* 8/(Time spent in steady-state phase after ramp-up+Time for the TCP/IP ramp-up process)

-   -   If message size*8<=Amount sent during linear ramp-up, then         Message Transmission Time=square-root(2*message-size*8/Slope)     -   If message size>Amount sent during linear ramp-up, then         Message Transmission Time=Time spent in steady-state phase after         ramp-up+Time for the TCP/IP ramp-up process     -   Where messages are contained in a continuous stream,         Tput_(avg) (Throughput)=TCP/IP receive window size*8/measure         network round-trip time between transfer end-points

The Message Queue And Database Response Time Model 320 may calculate the time to send a message using the above formulae if messaging is synchronous/sequential. The time to send a singular message, that is, the message-transmission time, may be computed as message size/throughput. The throughput may be the throughput during steady-state. In an embodiment of the invention, the throughput may be the average throughput. The messaging rate may be 1/message-transmission time

In an embodiment of the invention, if asynchronous/batching of messages is used, the message transmission time may be calculated using the above formulae but the traffic patterns may contain overlapping transfer. The message transmission time to send a singular message may be computed as message-size/throughput. The data rate when a message is being transmitted, the intra-messaging data rate, may be computed as the throughput. The throughput may be the throughput during steady-state. In an embodiment of the invention, the throughput may be the average throughput.

The Message Queue And Database Response Time Model 320 may then generate one or more model specific outputs. Examples of Message Queue And Database Response Time Model specific output include, but are not limited to, the time to transfer a message of specified size (message transmission time) based on presumed default setting parameters and user-specified message size, intra-messaging data rate of the network, the messaging rate that can be achieved if the messaging is synchronous/sequential, etc. An example of a model-specific output for a Message Queue And Database Response Time Model 320 is described in greater detail in reference with FIG. 7B.

The Message Delay and Variation Model 330 may use the following information: network round-trip time, transfer protocol (e.g., TCP, User Datagram Protocol (UDP), etc.), inter-message time for messages within a stream, and message size estimates. The Message Delay and Variation Model 330 may model streaming flow by computing several metrics. The metric computations may depend on the transport protocol used in the network route. For example, if UDP is used, the following computations may be utilized: Data Rate=message-size/inter-message-time

The data range may then be reported to the user along with one or more warnings about link saturation if data-rate exceeds links speeds in the network route.

In an embodiment of the invention, if TCP is used, and the inter-message-time is greater than twice of the round-trip-time, a warning flag may be set. The object transmission time may be calculated as follows:

-   -   If streaming message size*8<=Amount sent during linear ramp-up,         then         Object Transmission Time=square-root(2* streaming message         size*8/Slope)     -   If streaming message size>Amount sent during linear ramp-up,         then         Object Transmission Time=Time spent in steady-state phase after         ramp-up+Time for the TCP/IP ramp-up process

In an embodiment of the invention, if the object transmission time is greater than the inter-message-time, then a warning may sent to the user that either there need to be concurrent overlapping TCP connections so that messages can be sent concurrently OR a queue will build up in the sender end-system (server/PC) because messages are being generate faster than TCP can deliver them.

The Message Delay and Variation Model 330 may further compute the steady-state throughput as follows: Tput_(ss) (Throughput)=TCP/IP receive window size*8/measure network round-trip time between transfer end-points

The Message Delay and Variation Model 330 may further compute how long it may take to transmit 64 Kb, that is, the 64 Kb transmission time. The 64 Kb transmission time may be computed as follows: 64 KB transmission time=square-root(2*64000*8/m),

-   -   where m=(64000*8/rtt)/(6*rtt) and rtt=round-trip-time between         transfer end-points

The Message Delay and Variation Model 330 may then generate one or more model specific outputs. Examples of Message Delay and Variation Model specific output include, but are not limited to, warnings on whether the message stream will have performance problems due to TCP slow starts, the time required to transmit the message size specified, warnings on the fact that the transmission time will be affected by whether or not the messages are long enough to overcome the TCP slow-start phase if the idle time between messages is larger than a couple-few round-trip-times, the data rate that can be achieved after TCP has reached its steady-state phase (Tput_(ss)), and a warning if the time between messages is greater than the time to send one message—indicating that a sending queue will build during stream operation. The Message Delay and Variation Model 330 may also report the data rate that the stream will place onto the network and warn that if this is higher than link speeds for the route that network congestion will occur. An example of a model-specific output for a Message Delay and Variation Model 330 is described in greater detail in reference with FIG. 8B.

The Market Data Distribution Model 340 may use the following information: number of hops in the route from source to consumers, network round-trip time, transfer protocol (e.g., TCP, UDP, etc.), and message size estimates. The Market Data Distribution Model 340 may model individual route hops by computing several metrics. Examples of metrics include, but are not limited to, the latency or delay in sending a message packet from the source to the consumer over a network route, the time to serialize or transmit a message packet over each hop/link in a network route, and switching delays due to network switches in the route. The time to serialize or transmit a message packet over each hop/link in a network route may be calculated by using the link speed for each hop/link in a network route and calculating the time to transmit a message from the source or network switch to the next recipient of a packet. The next recipient of the packet may be a network switch, a final message consumer, a server, or a processor. The Market Data Distribution Model 340 may then compute the serialization-time-per-hop using the following formula: Serialization-time-per-hop (if the link is a 1Gigabit/second link)=minimum (maximum-possible message size, message size*1.15)*8/10**9

Other divisors may be used for different link speeds. The Market Data Distribution Model 340 may compute the switching delays due to network switches in the route using product information or other sources for the switch products used in the network route.

In an embodiment of the invention, the Market Data Distribution Model 340 may model the entire network route by computing several metrics. The metric computations may depend on the transport protocol used in the network route. For example, if the User Datagram Protocol (UDP) is used, the following computations may be utilized: Total Serialization Time for the route=(number-of-hops+1)*serialization-time-per-hop, if each link is the same speed (1 Gbit/sec, for example) Total Switching Latency for the route=number-of-hops*switching-delay-per-hop

In an embodiment of the invention, the Market Data Distribution Model 340 may calculate each route hop individually and then add them to determine the Total Serialization Time for the route.

In an embodiment of the invention, if the protocol is TCP, the following computations may be utilized: Flow-controlled Message Delivery Time=message-size*8/throughput Message Remainder (amount of the message which has not fit into the first network Maximum Transmission Unit (MTU) packets of size 1500 bytes)=message-size−1500*Int(message-size/1500), where Int(a/b) is the integer portion of a/b Route Serialization Time for the Last Part of the Message=(number-of-hops+1)*message-remainder*8*1.15*10**9 (for 1 Gbit/sec links, for example) Effective Serialization Time for the route=Flow-controlled Message Delivery Time+Route Serialization Time for the Last Part of the Message

The Market Data Distribution Model 340 may then generate one or more model specific outputs. Examples of Market Data Distribution Model specific output include, but are not limited to, the amount of time spent transmitting/serializing the messages through the entire route, the amount of time spent in switching delays through the entire route, the amount of time spent traveling over distance (the one-way measured latency minus the sum of the above values), etc. An example of a model-specific output for a Message Queue And Database Response Time Model 320 is described in greater detail in reference with FIG. 9B.

The Streaming Model 350 may use the following information: network round-trip time, transfer protocol (e.g., TCP, User Datagram Protocol (UDP), etc.), inter-message time for messages within a stream, and message size estimates. The Streaming Model 350 may model streaming flow by computing several metrics. The metric computations may depend on the transport protocol used in the network route. For example, if UDP is used, the following computations may be utilized: Data Rate=message-size/inter-message-time

The data range may then be reported to the user along with one or more warnings about link saturation if data-rate exceeds links speeds in the network route.

In an embodiment of the invention, if TCP is used, and the inter-message-time is greater than twice of the round-trip-time, a warning flag may be set. The object transmission time may be calculated as follows:

-   -   If streaming message size*8<=Amount sent during linear ramp-up,         then         Object Transmission Time=square-root(2*streaming message         size*8/Slope)     -   If streaming message size>Amount sent during linear ramp-up,         then         Object Transmission Time=Time spent in steady-state phase after         ramp-up+Time for the TCP/IP ramp-up process

In an embodiment of the invention, if the object transmission time is greater than the inter-message-time, then a warning may sent to the user that either there need to be concurrent overlapping TCP connections so that messages can be sent concurrently OR a queue will build up in the sender end-system (server/PC) because messages are being generate faster than TCP can deliver them.

The Streaming Model 350 may further compute the steady-state throughput as follows: Tput_(ss) (Throughput)=TCP/IP receive window size*8/measure network round-trip time between transfer end-points

The Streaming Model 350 may further compute how long it may take to transmit 64 Kb, that is, the 64 Kb transmission time. The 64 Kb transmission time may be computed as follows: 64 KB transmission time=square-root(2*64000*8/m),

-   -   where m=(64000*8/rtt)/(6*rtt) and rtt=round-trip-time between         transfer end-points

The Streaming Model 350 may then generate one or more model specific outputs. Examples of Streaming Model specific output include, but are not limited to, warnings on whether the message stream will have performance problems due to TCP slow starts, the time required to transmit the message size specified, warnings on the fact that the transmission time will be affected by whether or not the messages are long enough to overcome the TCP slow-start phase if the idle time between messages is larger than a couple-few round-trip-times, the data rate that can be achieved after TCP has reached its steady-state phase (Tput_(ss)), and a warning if the time between messages is greater than the time to send one message—indicating that a sending queue will build during stream operation. The Streaming Model 350 may also report the data rate that the stream will place onto the network and warn that if this is higher than link speeds for the route that network congestion will occur. An example of a model-specific output for a Streaming Model 350 is described in greater detail in reference with FIG. 10B.

As used herein, the term “processing machine” is to be understood to include at least one processor that uses at least one memory. The at least one memory stores a set of instructions. The instructions may be either permanently or temporarily stored in the memory or memories of the processing machine. The processor executes the instructions that are stored in the memory or memories in order to process data. The set of instructions may include various instructions that perform a particular task or tasks, such as any of the processing as described herein.

Accordingly, the user interface is any device that provides communication between a user and a processing machine. The information provided by the user to the processing machine through the user interface may be in the form of a command, a selection of data, or some other input, for example.

As discussed above, a user interface is utilized by the processing machine that performs a set of instructions such that the processing machine processes data for a user. The user interface is typically used by the processing machine for interacting with a user either to convey information or receive information from the user. However, it should be appreciated that in accordance with some embodiments of the system and method of the invention, it is not necessary that a human user actually interact with a user interface used by the processing machine of the invention. Rather, it is also contemplated that the user interface of the invention might interact, i.e., convey and receive information, with another processing machine, rather than a human user. Accordingly, the other processing machine might be characterized as a user. Further, it is contemplated that a user interface utilized in the system and method of the invention may interact partially with another processing machine or processing machines, while also interacting partially with a human user.
